We need to find the confidence interval for the SLEEP variable.
To do this, we need to find the mean and standard deviation with
the Week 1 spreadsheet. Then we can the Week 5 spreadsheet to find
the confidence interval.
First, find the mean and standard deviation by copying the SLEEP
variable and pasting it into the Week 1 spreadsheet. Write down the
mean and the sample standard deviation as well as the count. Open
the Week 5 spreadsheet and...
